Sequential EFI System

True sequential EFI with individual cylinder trim which offers more precise control compared to batch-fire/bank-to-bank systems.

Computing Power

A robust ECU that utilizes our OEM standard 32-bit architecture. This allows the system to manage input/output signals, voltage, and RPM faster and more consistently than our competitors.

Plug 'n' Play

Not a tuning wiz? You don't need to be since we provide a wizard for you. Our self-learning* functionality means you only have to answer a few basic questions in the startup wizard and then the ECU takes care of the rest. After about 30-60 mins of idling and drive time, the system will build it's own tune so you don't have to. Click here to learn more about our handhelds and dashes and see all of their features.

*Self-learn works best for stock-mild applications. For more aggressive applications and even some stock-mild applications, we offer free tuning software on our website.

It takes two.

The Wild Card EFI system utilizes two WBO2 sensors to read each bank of your V8 engine. Dual wide-band sensors allow precise calibration of each cylinder bank, optimizing performance and allowing more thorough tuning of your engine without any compromises.
